Allow CONFIG_CLK_RENESAS to be set without bringing in RCAR-GEN2/3 code.
CONFIG_RENESAS is used in drivers/clk/Makefile to control recursion into the drivers/clk/renesas subdirectory. It also controls compilation of renesas-cpg-mssr.c support code for the RCAR-GEN2 and RCAR-GEN3 devices.
The support code contains platform specific hardware access (TMU_BASE), and it is not needed for other Renesas devices such as RZ/N1. Therefore, alter Makefile to build renesas-cpg-mssr.c only for RCAR-GEN2/3.

Why not move the renesas-cpg-mssr.o into obj-$(CONFIG_CLK_RCAR_CPG_LIB) line instead ? I suspect RZN1 is not using the CPG lib anyway ?
